The distance d (in feet) a penny falls from the window of a building is represented by d = 16t^2 where t is the time (in seconds

steposvetlana [31]

Answer:

5 seconds

Step-by-step explanation:

d = 16t^2

You are given the distance, d, and you need to find the time, t. Replace d with the given distance, 400 ft.

d = 400

400 = 16t^2

Switch sides.

16t^2 = 400

Divide both sides by 16.

t^2 = 25

Take the square root of both sides.

t = 5

Answer: 5 seconds

Mrs.Lohens made curtains for her children’s bedrooms. She used 4 3/4 yards of fabric for Nickys room and 6 5/8 yards for Linda’s

Gelneren [198K]

Answer:

$11\frac{3}{8}\ yd$

Step-by-step explanation:

we know that

To find out the total yards of fabric used, add up the yards of fabric used for Nickys' room and the yards of fabric used for Linda's room

$4\frac{3}{4}+6\frac{5}{8}$

Convert mixed number to an improper fraction

$4\frac{3}{4}\ yd=4+\frac{3}{4}=\frac{4*4+3}{4}=\frac{19}{4}\ yd$

$6\frac{5}{8}\ yd=6+\frac{5}{8}=\frac{6*8+5}{8}=\frac{53}{8}\ yd$

Adds the fractions

$\frac{19}{4}+\frac{53}{8}=\frac{2*19+53}{8}= \frac{91}{8}\ yd$

Convert to mixed number

$\frac{91}{8}\ yd= \frac{88}{8}+ \frac{3}{8}= 11\frac{3}{8}\ yd$
